IMPROVEMENT IN DYERS VATS.

TO ALL WHOM IT MAY CONQERN:

Be it known that we, WILLIAM VINE und WILLIAM H. JUBB, both of the town of Norwalk, county of Fairiichl, and State of Connecticut, havo invented new and usel'ul Improvements in the Modo of Constructing Dyers Vats; and we do hereby declare that the following is a full and exact description thereof, reference bring had te the accompanying drawing, and to the letters of reference marked thereon.

The nature of our invention consists in the construction und arrangement of a. double vat, with attachments for lifting up the inner vat. i

To enable others skilled in the nrt to make and use our invention,' we will proceed to describe the same. The drawing i Figure 1, is a sectional view oi' the double vat, showingthe'satne when in use with the dye'stui in.

Figure 2, u view of the same when the inner vat and contents are raised up to drain oil' the liquid dye into the lower or main vat, to'be used again. i

We construct theouter or main vat, A, in the usual manner. The inner rat, B,4wo construct of stares and hoops, at' the saine description as the outer vat A. In the side we make bevellcd vertical openings, C, or their equivalents, at the necessary distance apart for the liquid dye to pass through and run down intothe outer vat A when thc rat is lifted up, as shown in tig. 2. The bottom is also perforated with holes for the same purpose. We also make an opening in the side for theieonvenicncc of taking cut the dyed wool or other article when drained.

On the top edge of the inner vnt B is a wide, rounded rim, D, which covers the edges ofboth the rats when down, making in appearance one vat, so that there is no obstruction to tl1estirring, working, or mixing the'dye'-stufl` and materials.

The arrangements for hoisting` up the inner rat B are as follows: We place four nprights, E, to support the rollers, pulleys, 85e., i'or hoisting'nnd guiding the same. 'lhe roller F extends across tho whole length, for the ropes or chains M to rerolvo on, with hooksfani'i eyes II attached to the rim D of the inner vat. On the outside of the outer vat is the arrangement for hoisting, beingl n. roller, I, with ratchet und pawl K, crank L. There are other equivalent devices which w'c can use in some cases for hoisting, such as takingr away the upright, E, and using a pulley overhead, &e., but it will not interfere with our principle. 'lhe inner vat B may in some cases be composed ol` open wire or basket-work, as an' equivalent for wood, and the other arrangements remain the same.

The utility of our invention is as follows: In dyeing wool or other fibrous material in large quantities, the

usc of the single vat is sometimes of great inconvenience and loss, both in dyeing-materials and labor. In taking out the wool or other article from the hot boiling dye-liquor, in small portions at a time,'\vhich we are obliged to rlo in most eases when it has been in just the required length of`tiine, the portion left to the last will in sonic cases receive a different hue from that taken out first, which is, in delicate colors, of great and injurious importance. In our improvement the whole mass is hoisted out instantly, and is drained and cooled without any trouble, securing to a certainty an evenness of color. '.lhe saving of the liquid hot dye, in the single vat. has to be drawn off by a pipe and faucet, or some similar device, thus wasting the dye-liquor, which in'most cases isdaI verycostly article- Mixing and preparing another quantity ofeold dyeing-liquidof the same color is attended with great expense in lahor and fuel to bring it up to a boiling-point again.

In dyeing with mixed'or anilincor compound colors, the liquid of' the iirst process is retained in vat Afor any length of time to receive other coloring-mutter, to be added as the case may require, and then the vat, B

and contents can be lowered instantly, or .at any time required; in blue-vate, the change required is instan- ,tztieous to secure perfect evenness of color.

What we claim as our invention, and desire to secure by Letters Patent, is- The arrangement of the double vat A and B with lioistingattachments, in the manner substantially as herein set forth and for the purposel described. I I
